Cylinder and control component

A cylinder, comprising two mirror-symmetric cylinder mechanisms which jointly drive a latchbolt control ring;

• wherein the latchbolt mechanism comprises an electric locking ring and a control pillar, wherein the control pillar passes through the rotation centers of the electric locking ring and the latchbolt control ring one after another;
• wherein one of the two control rods is provided at its front surface with a rotatable shaft and the other is provided at the front surface with a counter bore, wherein the rotatable shaft is inserted into the counter bore and may rotate inside it, wherein the rotatable shaft passes movably through the latchbolt control ring and the latchbolt control ring may rotate around the rotatable shaft;
• wherein each of the two control rods is equipped with a first control pin and a second control pin, wherein the first control pin and the second control pin circulates around the rotatable shaft, wherein the rotation direction, in which the first control pins controls the latchbolt control ring to unlatch, corresponds to the rotation direction, in which the second control pin controls the latchbolt control ring to unlatch;
• wherein the first control pin passes in sequence through the electrical unlocking cam of the first mirror symmetric side, the mechanical locking ring of the first mirror symmetric side, the electrical locking ring of the first mirror symmetric side, the latchbolt control ring and the electrical locking ring of the second mirror symmetric side, wherein the electrical locking ring of the second side controls the unlocking and locking movement of the first control pin and the electrical locking ring of the first mirror symmetric side does not limit the unlatching movement of the first control pin;
• wherein the second control pin passes in sequence through the electrical unlocking cam of the second mirror symmetric side, the mechanical locking ring of the second mirror symmetric side, the electrical locking ring of the second mirror symmetric side, the latchbolt control ring and the electrical locking ring of the first mirror symmetric side, wherein the electrical locking ring of the first mirror side controls the unlocking and locking movement of the second control pin and the electrical locking ring of the second mirror side does not limit the unlatching movement of the second control pin.
